Published: April 19, 2025

This article explores the foundational principles of ionizing radiation and provides a comprehensive overview its impact on thermoplastic polymers. Ionizing radiation, encompassing gamma rays, X-rays, electron beams, has been extensively studied due to capacity alter molecular structure These changes enable advancements in various applications by promoting crosslinking, controlled degradation, grafting, crystallinity adjustments. The delves into fundamental mechanisms polymer interactions, including ionization, electronic excitation, free radical formation. It highlights how these processes lead structural transformations that enhance physical, thermal, mechanical properties Factors such as type, absorbed doses, temperature, environmental conditions are discussed context their role controlling modifications. Key practical identified across fields medicine, food packaging, aerospace, industry. Examples include production sterilizable medical devices, enhanced packaging for longer shelf life, radiation-resistant materials aerospace nuclear sectors. Despite many advantages, also emphasizes challenges process variability, sensitivity standardization difficulties. review underscores emerging research directions, optimizing irradiation parameters integrating advanced characterization techniques like Fourier Transform Infrared Spectroscopy (FT-IR) X-ray diffraction (XRD). development new blends composites, designed irradiation-induced property enhancement, represents promising area innovation.
